Question 254535
We can tell immedidately that the vertex is at points (-5,-1).

Rearranging to find the roots (where the graph crosses the x axis) we get {{{1/4=(x+5)^2}}} plus or minus {{{sqrt(1/4)-5=x}}} so we know that the roots are {{{1/2-5=-4.5}}} and {{{-1/2-5=-5.5}}}

{{{ graph( 400, 400, -10, 2, -5, 5, 4(x+5)^2-1) }}}
